Intended Use
The SMA I/O Module is a module with 6 digital inputs and 1 digital output operating as a multifunction relay. The
SMA I/O Module enables the implementation of grid management services for up to 12 SMA inverters in a network
with the same system password. The SMA I/O Module must be installed in one SMA inverter. For the implementation
of grid management services, the SMA I/O Module receives the specifications of the grid operator via a ripple control
receiver. The SMA I/O Module transmits the specifications of the grid operator via Speedwire network to a maximum
of 11 further SMA inverters. The multifunction relay can be configured for various operating modes. The multifunction
relay can, for example, be used for switching fault indicators on and off.
The product must only be installed in the following SMA inverters:
• STP 50-40 (Sunny Tripower CORE1)
• STP 50-41 (Sunny Tripower CORE1)
• STP 50-JP-40 (Sunny Tripower CORE1-JP)
The inverter still complies with the standard after the product has been installed.
All components must remain within their permitted operating ranges and their installation requirements at all times.
The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the
grid operator.
